Description
- The present invention relates to a resin component formed by vibration welding together first and second molded bodies that are both molded from a synthetic resin.
- Conventionally, the aforesaid resin component is known in, for instance, Japanese Patent Unexamined Publication No. Hei. 7-266425, and in the resin component disclosed therein, in order to prevent a damage to the commercial value of the resin component by burrs that are produced to be exposed from an external surface of the resin component when the fist and second molded bodies are vibration welded together, a flat joint area is provided on one of the two molded bodies, while provided on the other molded body are a welding projection adapted to be vibration welded to the joint area at a distal end thereof and a regulating projection disposed outwardly of the vibration welding portion and adapted to abut against the joint area when vibration welding of the vibration welding portion to the joint area is completed, so that burrs produced to project outwardly when the welding projection is vibration welded to the joint area are contained within a space formed between the welding projection and the regulating projection to thereby be prevented from exposure to the outside.
- In the above-described conventional resin component, since there exists a gap between the regulating projection and the joint area before the vibration welding is completed, burrs produced in conjunction with vibration welding of the welding projection to the joint area before the vibration welding is completed are guided by the flat guide surface to be exposed to the outside through the gap, this leading to a possibility that the burrs are exposed to the outside or held between the regulating projection and the joint area after the vibration welding is completed, thus it being not possible to securely prevent the exposure of the burrs to the outside.
- The present invention was made in view of the problem described above, and an object thereof is to provide a resin component in which exposure of burrs produced when first and second molded bodies are vibration welded to the outside is securely be prevented to thereby improve the commercial value of the resin component.
- The above-mentioned object can be achieved by a resin component according to the present invention comprising a first synthetic resin molded body and a second synthetic resin molded body coupled with the first synthetic resin molded body by a vibration welding. The first resin molded body includes an joint area which is provided at its edge portion where the first molded body is joined to the second molded body, a first regulating projection which is provided from an outermost edge of the joint area toward the second molded body, and a first guide surface connecting an internal side surface of the first regulating projection to the joint area. The second resin molded body includes a welding projection which is projected toward the first molded body so as to be welded at a distal end thereof to the joint area of the first molded body and is provided at its edge portion where the second molded body is jointed to the first molded body, a second regulating projection which is projected from an outermost edge of the second molded body toward the first molded body so as to closely confront the first regulating projection after a vibration welding operation between the welding projection and the joint area is completed, and a second guide surface connecting an external side surface of the welding projection to an internal side surface of the second regulating projection.
- In the resin component according to the present invention, it is preferable that the first guide surface is formed into a curve shape to guide a burr produced to project toward the first regulating projection as a result of vibration welding of the welding projection to the joint area toward the internal side surface of the second regulating projection along the internal side surface of the first regulating projection, and the second guide surface is curved and located in confront with the first guide surface so as to guide the burr guided from the internal side surface of the first regulating projection to the internal side surface of the second regulating projection toward the external side surface of the welding projection.
- In addition, in the resin component according to the present invention, it is also preferable that each of the joint area, the first regulating projection, the welding projection and the second regulating projection is formed into an endless shape.
- Further, in the resin component according to the present invention, it is advantageous that the distal end of the welding projection has a cross section substantially formed by two line one of which is inclined relative to a direction extended perpendicular to the joint area by a first predetermined angle (α) and the other of which is extended along or inclined relative to the direction by a second predetermined angle (β) smaller than the first predetermined angle.
- Moreover, in order to attaining the above object, according to the present invention, there is provided a resin component formed by vibration welding together first and second molded bodies that are molded from a synthetic resin, wherein there are provided at an edge portion of the first molded body where the first molded body is joined to the second molded body an endless joint area, a first endless regulating projection projecting from an outer edge of the joint area toward the second molded body and a first guide surface connecting an internal side surface of the first regulating projection to the joint area, wherein there are provided at an edge portion of the second molded body where the second molded body is jointed to the first molded body, an endless welding projection projecting toward the first molded body in such a manner as to be welded at a distal end thereof to the joint area of the first molded body, a second endless regulating projection projecting from an outer edge of the second molded body toward the first molded body in such a manner as to closely confront the first regulating projection when vibration welding of the welding projection to the joint area is completed and a second guide surface connecting an external side surface of the welding projection to an internal side surface of the second regulating projection, the first guide surface being curved convexedly outwardly in such a manner as to guide a burr produced to project toward the first regulating projection as a result of vibration welding of the welding projection to the joint area toward the internal side surface of the regulating projection along the internal side surface of the first regulating projection, and the second guide surface being curved convexedly to aside opposite to the first guide surface in such a manner as to guide the burr guided from the internal side surface of the first regulating projection to the internal side surface of the second regulating projection toward the external side surface of the welding projection.
- According to the above construction, the first and second molded bodies are vibrated relative to each other at a high speed with the distal end of the welding projection of the second molded body being pressed against the joint area of the first molded body, whereby the distal end of the welding projection is vibration welded to the joint area by a friction heat produced between the distal end of the welding projection and the joine area to thereby construct the resin component. Of burrs produced at a contact portion between the distal end of the welding projection and the joint area during this vibration welding, those projecting outwardly are guided by the first guide surface along the internal side surface of the first regulating projection toward the second regulating projection, and furthermore burrs guided from the internal side surface of the first regulating projection to the internal side surface of the second regulating projection are then guided toward the external side surface of the welding projection by the second guide surface, and therefore the burrs are prevented from project outwardly from the gap between the first and second regulating projections and instead they are destined to be confined within the space formed by the joint area, the first regulating projection, the second regulating projection and the welding projection, whereby exposure of the burrs from the external surface of the resin component is securely prevented, this thereby contributing to the improvement of the commercial value of the resin component so formed.

- A mode of carrying out the present invention will be described below based on an embodiment according to the present invention shown in the accompanying drawings.
- FIGS.1 to 9 shown an embodiment of the present invention, in which FIG. 1 is a brake fluid pressure circuit diagram of a brake system for a passenger vehicle, FIG. 2 a side view of a brake fluid pressure control device, FIG. 3 a view seen in a direction indicated by an

second output ports pressure control device 3 provided between a front left wheel brake B1, a rear right wheel brake B2, a front right wheel brake B3 and a rear left wheel brake B4 and first and second output fluid pressure passages 2 1, 2 2 connected individually to the first andsecond output ports pressure reduction valves pressure control device 3 and the rear left and right wheel brakes B2, B4, respectively. - The brake fluid
pressure control device 3 comprises first, second, third and fourth normally openedelectromagnetic valves 5 1 to 5 4 disposed so as to correspond individually to the front left wheel brake B1, rear right wheel brake B2, front right wheel brake B3 and rear left wheel brake B4, first, second, third andfourth check valves 7 1 to 7 4 connected, respectively, in parallel to the normally openedelectromagnetic valves 5 1 to 5 4, first, second, third and fourth normally closedelectromagnetic valves 6 1 to 6 4 disposed so as to correspond individually to the respective wheel brakes B1 to B4, first and second reservoirs 8 1, 8 2 disposed so as to correspond individually to the first and second output fluid pressure passages 2 1, 2 2, first and second plunger-type pumps electric motor 12 for driving both of thepumps second pumps electronic control unit 16 for controlling operations of the respective normally openedelectromagnetic valves 5 1 to 5 4, the respective normally closedelectromagnetic valves 6 1 to 6 4 and the electric motor. - The first normally opened
electromagnetic valve 5 1 is provided between the first output fluid pressure passage 2 1 and the front left wheel brake B1, the second normally openedelectromagnetic valve 5 2 between the first output fluid pressure passage 2 1 and the first proportionalpressure reduction valve 4 1, the third normally openedelectromagnetic valve 5 3 between the second output fluid pressure passage 2 2 and the front right wheel brake B3, and the fourth normally openedelectromagnetic valve 5 4 between the second output fluid pressure passage 2 2 and the second proportionalpressure reduction valve 4 2. - In addition, the first to
fourth check valves 7 1 to 7 4 are connected, respectively, in parallel to the normally openedelectromagnetic valves 5 1 to 5 4 in such a manner as to allow flows of brake fluid from the corresponding wheel brakes B1 to B4 to the master cylinder M. - The first normally closed
electromagnetic valve 6 1 is provided between the front left wheel brake B1 and the first reservoir 8 1, the second normally closedelectromagnetic valve 6 2 between the first proportionalpressure reduction valve 4 1 and the first reservoir 8 1, the third normally closedelectromagnetic valve 6 3 between the front right wheel brake B3 and the second reservoir 8 2, and the fourth normally closedelectromagnetic valve 6 4 between the second proportionalpressure reduction valve 4 2 and the second reservoir 8 2. - Now, the first normally opened
electromagnetic valve 5 1 cooperates with the first normally closedelectromagnetic valve 6 1 to constitute a first control valve means V1, the second normally openedelectromagnetic valve 5 2 with the second normally closedelectromagnetic valve 6 2 to constitute a second control valve means V2, the third normally openedelectromagnetic valve 5 3 with the third normally closedelectromagnetic vale 6 3 to constitute a third control valve means V3, and the fourth normally openedelectromagnetic valve 5 4 with the fourth normally closedelectromagnetic valve 6 4 to constitute a fourth control valve means V4. - The control valves V1 to V4 constructed as described above are controlled by the
electronic control unit 16 so as to establish communications between the master cylinder M and the wheel brakes B1 to B4 and to close communications between the wheel brakes B1 to B4 and the reservoirs 8 1, 8 2 during a normal braking operation in which there is no possibility that the respective wheels are locked. In other words, the respective normally openedelectromagnetic valves 5 1 to 5 4 are deenergized to be kept in opened conditions and the respective normally closedelectromagnetic valves 6 1 to 6 4 are also deenergized to be kept in closed conditions, and a brake fluid pressure outputted from thefirst output port 11 of the master cylinder M is applied to the front left wheel brake B1 via the normally openedelectromagnetic valve 5 1 and also to the rear right wheel brake B2 via the second normally openedelectromagnetic valve 52 and the first proportionalpressure reduction valve 4 1. In addition, a brake fluid pressure outputted from thesecond output port 12 of the master cylinder M is applied to the front right wheel brake B3 via the third normally openedelectromagnetic valve 5 3 and also to the rear left wheel brake B4 via the fourth normally openedelectromagnetic valve 5 4 and the second proportionalpressure reduction valve 4 2. - When any of the wheels is about to be locked during the above braking operation, of the control valve means V1 to V4 the control valve means corresponding the wheel which is about to be locked is controlled by the
electronic control unit 16 so as to close communications between the master cylinder M and the wheel brakes B1 to B4 and to establish communications between the wheel brakes B1 to B4 and the reservoirs 8 1, 8 2. In other words, of the first to fourth normally openedelectromagnetic valves 5 1 to 5 4, the normally opened electromagnetic valve corresponding to the wheel which is about to enter into a locked condition is energized to be closed, while of the first to fourth normally closedelectromagnetic valves 6 1 to 6 4 the normally closed electromagnetic valve corresponding to the wheel in question is energized to be opened, whereby a part of the brake fluid pressure of the wheel which is about to enter into the locked condition is absorbed by either the first reservoir 8 1 or the second reservoir 8 2, the brake fluid pressure of the wheel which is about to enter into the locked condition being thereby reduced. - In trying to hold the brake fluid pressures constant, the respective control valves V1 to V4 are controlled by the
electronic control unit 16 such that the wheel brakes B1 to B4 are cut off from the master cylinder M and the reservoirs 8 1, 8 2. In other words, the normally openedelectromagnetic valves 5 1 to 5 4 are energized to be closed while the normally closedelectromagnetic valves 6 1 to 6 4 are deenergized to be kept closed. Furthermore, in trying to boost the brake fluid pressures, the normally openedelectromagnetic valves 5 1 to 5 4 are deenergized to be kept opened and the normally closedelectromagnetic valves 6 1 to 6 4 are deenergized to be kept closed. - Thus, efficient braking becomes possible without locking the wheels by controlling the respective control valves V1 to V4 by the
